Please, solve this question as detailed as possible

Determine the final temperature when 25ml of a 2M iron trichloride solution and 25ml of a 2M sodium hydroxide are mixed in a calorimeter. The temperature of both solutions before mixing is 21C. The heat capacity of the calorimeter is 20J/C. Assume that volumes are additive and that the specific heat and density of the solutions are the same as that of water. Write down all the reaction equations needed to solve this exercise
